Direction (Q. 6 - 10): In each question below are given three statements followed by three conclusions numbered I, II and III. You have to take the given statements to be true even if they seem to be at variance with commonly known facts. Read all the conclusions and then decide which of the given conclusions logically follows from the given statements disregarding commonly known facts.
Statements: All desks are rooms. Some rooms are halls.
All halls are leaves.
Conclusions: I. Some leaves are desks.
II. Some halls are desks.
III. Some leaves are rooms.
All desks are rooms + Some rooms are halls = A + I = no conclusion. Hence II does not follow. Some rooms are halls + All halls are leaves = I + A = 1. Hence III follows. Some leave are rooms + conversion of All desks are rooms = I + I = no conclusion. Hence I does not follow.
All stones are rivers + All rivers are cars = A + A = A = All stones are cars - conversion - Some cars are stones (I). Hence II followss. All rivers are cars + Some cars are trains = A + I = No Conclusion. Hence III and I do not follow.
All building are mirrors + Some mirrors are pens = A + I = No conclusion. Hence II does not follows. Some mirrors are pens + No pen is papers = I + E = O = Some mirrors are not papers. Hence III follows. All buildings are mirrors + Some mirrors are not papers = A + O = No conclusion. Hence I does not follow.
Some books are trees + All trees are roads = I + A = I = Some books are roads. Hence I follows. All trees are roads + All roads are wheels = A + A = A = All trees are wheels. Hence II follows. But, All wheels are trees does not follows.
